/*
this file deals with qc builtins to apply custom skeletal blending (skeletal objects extension), as well as the logic required to perform realtime ragdoll, if I ever implement that.
*/
/*
skeletal objects are just a set of bone poses.
they are separate from the entity they are attached to, and must be created/destroyed separately.
typically the bones are all stored relative to their parent.
qc must use skel_build to copy animation data from the file format into the skeletal object for rendering, but can build different bones using different animations or can override explicit bones.
ragdoll file is a description of the joints in the ragdoll.
a skeletal object, built from a doll instead of a model, has a series of physics objects created at key points (ie: not face).
these objects are absolute
qc must build the skeletal object still, which fills the skeletal object from the physics objects instead of animation data, for bones that have solid objects.
